摘要
本文应用窄带物联网LoRa通信技术,构建海洋环境下水面自主网络,解决了目前海洋通信过程中成本高、覆盖范围不足以及功耗高等问题;本文设计了一种基于窄带物联网LoRa通信机制的海洋水质监测系统,能实时采集海域PH值、溶氧量、水温、流速等数据,数据经由窄带自组网络发送至基站,并通过公共网络传输到云端.论文还在宁德三都澳海域对海域水质监测系统进行了应用实验,取得了良好的效果,实验表明该系统对海域水质监测具有的实际应用价值.
In this paper,LORA communication technology of the narrow-band Internet of Things is applied to build an autonomous surface network under the ocean environment,which solves the problems of high cost,insufficient coverage and high power consumption in the current ocean communication process.A based on LoRa communication mechanism of sea water quality monitoring system is designed in this paper,which can collect pH value,dissolved oxygen,water temperature,flow rate and other data in real time.The data is sent to the base station via a narrowband ad-hoc network and to the cloud via a public network.The paper also carried out the application experiment of the water quality monitoring system in Ningde Sanduao sea area,and achieved good results.The experiment shows that the system has practical application value for the water quality monitoring.
